Get contacts for EWC 08 03 12*EWC 08 03 12* is a specific sub-code under EWC 07 03 — Wastes from manufacture, formulation, supply and use of organic dyes and pigments (excluding 06 11). The classification guidance below applies to this waste stream.
EWC 07 03 covers process wastes from organic dye and pigment chemistry — primarily azo dyes, reactive dyes, vat dyes, phthalocyanine pigments and organic lake pigments. Hazardous sub-codes include 07 03 01* (mother liquors), 07 03 03* (halogenated solvents), 07 03 04* (other solvents), 07 03 07* (halogenated still bottoms) and 07 03 08* (other still bottoms).
Azo dye synthesis generates amine-containing mother liquors — some aromatic amines (β-naphthylamine, benzidine) are carcinogenic and subject to REACH restriction. Phthalocyanine pigment synthesis involves phthalic anhydride, copper compounds and chlorine, producing copper-containing filter cake waste. Reactive dye manufacture generates sodium chloride and sodium sulphate mother liquors at high concentrations.
REACH Annex XVII (entry 43) restricts azo dyes that can release carcinogenic amines. Colour industry waste from textile dyeing operations is classified under 04 02, not here — 07 03 is specifically for manufacturing operations. Organic pigment waste recycling is limited due to complex composition; most streams route to high-temperature incineration.
Typical Generators
Established valorisation pathways for EWC 08 03 12*, ranked by economic value and market depth.
Solvent-containing streams (07 03 03*, 07 03 04*) distilled to recover usable solvent fraction. Recovered solvents (DMF, NMP, acetone) returned to process or sold to solvent recyclers. Still bottoms with high organic dye content treated as high-calorific waste.
Copper phthalocyanine production filter cake with significant Cu content (>2%) processed by copper hydrometallurgy — acid leach, solvent extraction and copper electrowinning. Recovered copper returned to phthalocyanine synthesis. Residual organic cake incinerated.
Azo dye mother liquors, amine-contaminated still bottoms and non-recoverable organic pigment waste incinerated at ≥1100°C with extended residence time. Carcinogenic amine content requires complete destruction. Scrubber effluent monitored for residual amines before discharge.
These are the established routes for EWC 08 03 12*. Which one your stream qualifies for depends on its composition, volume and region.
